Description


BACKGROUND OF THE INVENTION

This invention relates to a non-slip cushion for high chairs which prevents an infant from sliding out of the high chair and which additionally restricts squirming of the infant.

As has been well recognized in the art, the infant must assume a substantially erect posture when seated in a conventional high chair to avoid sliding forwardly or outwardly therefrom. The infant will not maintain the desired position if allowed to squirm. Various devices have been proposed to improve the posture of the infant or to otherwise prevent the infant from sliding out of the high chair. For instance, U.S. Pat. No. 4,712,833 illustrates a wedge-shaped cushion to prevent forward sliding of the infant. Also, U.S. Pat. No. 3,311,410 illustrates an anti-slip bar having a convex upper side to prevent forward sliding of an infant from a high chair.

Accordingly, it is an important object of the present invention to provide a non-slip high chair cushion which provides sufficient frictional force both between the cushion and the high chair seat and between the cushion and the bottom of the baby to prevent the baby from falling from the high chair.

Another important object of the invention is to provide a non-slip high chair cushion which covers a substantial portion of the upper surface of the high chair seat so as to provide a significant surface area of frictional resistance to movement of the cushion with respect to the high chair seat.

Another important object of the invention is to provide a non-slip high chair cushion having a scrim material which possesses resistance to deformation at right angles to each other.

SUMMARY OF THE INVENTION

It has been found that a non-slip high chair cushion may be provided which prevents an infant from sliding forwardly out of the high chair and which inhibits lateral squirming of the infant. The cushion includes a fabric constructed of a scrim material so as to possess substantial resistance to deformation in two directions at right angles to each other. The scrim forms openings in the fabric, which, in the preferred embodiment, are in a checkerboard pattern. Globules of rubbery polymeric material are deposited on the scrim as by dipping the scrim in a plastic foam material.

Cushions constructed in accordance with the invention are flexible so as to lie flat on the high chair seat. Said rubber polymeric material enables the cushion to maintain a high coefficient of friction both between the cushion and the high chair seat and between the cushion and the bottom of the baby to prevent the baby from falling from the high chair.

In a preferred embodiment, the cushion includes a binder in the form of a border portion which extends to form ties at the rear corners of the cushion for securement to a high chair back. The frictional force provided by the cushion aids in resisting horizontal forces which tend to move the cushion with respect to the high chair seat.

BRIEF DESCRIPTION OF THE DRAWINGS

The construction designed to carry out the invention will be hereinafter described, together with other features thereof.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings forming a part thereof, wherein an example of the invention is shown and wherein:

FIG. 1 is a perspective view illustrating a high chair non-slip cushion constructed in accordance with a preferred embodiment of the invention positioned upon the seat of a high chair;

FIG. 2 is a perspective view of a high chair non-slip cushion in accordance with the preferred embodiment of the invention, with polymeric coating partially broken away to reveal underlying scrim material,

FIG. 3 is a partial sectional elevation view taken along line 3--3 of FIG. 2, detailing the scrim material embedded within the polymeric material and a portion of a binder enclosing an exterior edge of the cushion; and

FIG. 4 is an enlarged perspective view further detailing the scrim material and related cushion construction.

DESCRIPTION OF A PREFERRED EMBODIMENT

The drawings illustrate a high chair non-slip cushion comprising a fabric made of scrim material A so as to possess substantial resistance to deformation in two directions at right angles to each other. The fabric has openings or enlarged open gaps B therein formed by the scrim, as shown in FIG. 2. Globules C of a rubbery polymeric material are deposited on the scrim as by dipping the scrim in a plastic foam material. A border portion D defines the shape of the cushion. The cushion is sufficiently flexible so as to lie flat clinging to a smooth high chair seat and to maintain a high coefficient of friction between the high chair seat and an infant. The infant is thereby protected against sliding or skidding out of a high chair.

Referring to FIGS. 1 and 2, the preferred embodiment of the high chair non-slip cushion is shown generally at 10 positioned upon the seat 12 of a high chair 11. The shape of the cushion 10 is defined by a binder 13 which in this instance forms a border portion D. Although the shape is shown in the figures as being substantially square, the cushion 10 may assume any shape which best cooperates with the shape of the high chair seat 12.

Referring to FIGS. 2 and 3, the preferred embodiment includes a binder 13 secured about the edges of the scrim A as by stitches 14. Additionally, the binder 13 extends at rear corners of cushion 10 to form ties 15 for securement to high chair back 16.

The high chair non-slip cushion 10 is formed by dipping scrim material A into a plastic foam material. This results in the formation of globules C of rubbery polymeric material, preferably polyvinyl chloride, distributed randomly in both directions about the yarn forming the scrim fabric A, as illustrated in FIGS. 1 and 2. The globules C are more pronounced at intersections of the yarn forming the scrim fabric as at C'. The fabric may contain added scrim in openings or enlarged open gaps B forming a checkerboard pattern over the fabric.

Suitable cushion material is provided by American Non-Slip Products, Inc., 2924-A Amwiler Road, Doraville, Ga. 30360 for use under rugs to prevent slipping. A preferred product is sold under the trademark MEGA-LOCK as a non-slip rug pad. This fabric is constructed from 150 denier polyester yarn and in dipped in liquid polyvinyl chloride which has been foamed in a standard foamer prior to dipping.

Because globules C possess a relatively high coefficient of friction as compared to the scrim and other yarn forming cushion covers, and because they reside on both top and bottom surfaces of cushion 10, a high coefficient of friction is provided both between the cushion and the high chair seat and between the cushion and the bottom of the baby, thereby preventing the baby from falling from the high chair. Moreover, the flat configuration of cushion 10 provides a significant surface area of contact; thus, the frictional forces generated by each globule C combine to constitute a resultant frictional force, which provides considerable resistance to movement of the cushion 10 with respect to seat 12 in any direction. Such a configuration likewise inhibits lateral squirming of an infant upon seat 12.

While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
